Justification:
|
This species has a large range, with an estimated global extent of occurrence of 1,000,000-10,000,000 km². The global population size has not been quantified, but the species is not believed to approach the thresholds for the population size criterion of the IUCN Red List (i.e. less than 10,000 mature individuals in conjunction with appropriate decline rates and subpopulation qualifiers), even though the species is described as 'uncommon' in at least parts of its range (del Hoyo et al. 1999). Global population trends have not been quantified; there is evidence of a population decline (del Hoyo et al. 1999), but the species is not believed to approach the thresholds for the population decline criterion of the IUCN Red List (i.e. declining more than 30% in ten years or three generations). For these reasons, the species is evaluated as Least Concern.
